Planet Bike
I won't claim expertise in thus subject area. I have not wanted more devices to charge, so I only own lights with non-rechargeable batteries. The Planet Bike Superflash taillight is on all my bikes. My most powerful headlights are from Planet Bike.
Other companies probably offer competitive products. I have not seriously shopped for a light for several years.
I have admired Planet Bikes' philosophy and advocacy.
I do not know about European availability. (though the name is "Planet ____")
